What Is Sheet Cladding?

Copper Clad Laminate (CCL) is a plate-like material made of electronic glass fiber cloth or other reinforcing materials impregnated with resin, coated with copper foil on one or both sides, and hot-pressed. Copper clad laminate. Various printed circuit boards with different forms and functions are selectively processed, etched, drilled, and plated with copper on copper-clad boards to make different printed circuits. The printed circuit board mainly plays the role of interconnection, insulation, and support, and has a great impact on the signal transmission speed, energy loss, and characteristic impedance in the circuit. Therefore, the performance, quality, and manufacturing of the printed circuit board Processability, manufacturing level, manufacturing cost, and long-term reliability and stability depend to a large extent on copper clad laminates.
